GABA has a powerful calming effect on the brain. Tranquilizers like Valium and Librium work by stimulating the brain's receptors for GABA. GABA inhibits anxiety by slowing down anxiety related messages between parts of the brain. Because GABA receptors reside throughout the body, as well as in the brain, GABA can have both a mentally and physically calming effect. When children are deficient in GABA, they often feel the same anxiety and restlessness that makes adults drink, crave sweets or succumb to food binges. In children, though, this anxiety and restlessness is often labeled as Attention Deficit Disorder, or ADD. [Control Hyperactivity A.D.D. Naturally, by B.J. Sahely, Ph.D., C.N.C, p.46-47]

Because GABA is known to play a central role in anxiety, some alternative practitioners suggest simply taking this amino acid as a supplement. However, no scientific evidence suggests that orally ingested GABA crosses the blood brain barrior (BBB).

Amino Acid: An organic acid containing nitrogen chemical building blocks that aid in the production of protein in the body. Eight of the twenty-two known amino acids are considered "essential," and must be obtained from dietary sources because the body can not synthesize them.

Hypertension: High blood pressure. Hypertension increases the risk of heart attack, stroke, and kidney failure because it adds to the workload of the heart, causing it to enlarge and, over time, to weaken; in addition, it may damage the walls of the arteries.

Inositol: Usually considered part of the vitamin B complex. It is thought that along with choline, inositol is necessary for the formation of lecithin within the body. Involved in calcium mobilization.

Metabolism: The chemical processes of living cells in which energy is produced in order to replace and repair tissues and maintain a healthy body. Responsible for the production of energy, biosynthesis of important substances, and degradation of various compounds.

Niacin: (Vitamin B-3): A coenzyme B-complex vitamin that assists in the breakdown of carbohydrates, fats and proteins. Essential for the health of the skin, nerves, tongue and digestive system. It is found in every cell of the body and is necessary for energy production. Niacin is also needed for DNA formation.
